Grid type soil moisture content monitoring system and method based on Internet of Things

Abstract

The invention discloses a grid type soil moisture content monitoring system and method based on the Internet of Things, and belongs to the field of farmland soil moisture content monitoring, the gridtype soil moisture content monitoring system comprises a soil temperature and humidity probe, a soil moisture content node, a soil moisture content gateway and a cloud server, and the soil temperatureand humidity probe transmits soil temperature and humidity data to the soil moisture content node; the soil moisture content node comprises a first LORA wireless module, a GPS module and a first MCUcontroller, and sends soil temperature and humidity data and GPS geographical location information to the soil moisture content gateway; the soil moisture content gateway comprises a second LORA wireless module, an Internet communication module and a second MCU controller which are in communication connection with the first LORA wireless module, and is used for summarizing data uploaded by all soil moisture content nodes and sending the data to the cloud server; and the cloud server comprises a data storage center and a big data analysis center which are used for storage and analysis. The soilmoisture content monitoring system solves the problems that an existing soil moisture content monitoring system is too high in equipment investment cost, a measurement mode has great contingency, andmeasurement is inaccurate.

Description

technical field [0001] The invention belongs to the field of farmland moisture monitoring, and relates to a network-based moisture monitoring system and method based on the Internet of Things. Background technique [0002] Moisture refers to the amount of water in the soil of the crop plough layer, moisture refers to the moisture of the soil, and moisture refers to the moisture of the soil. At present, China's agricultural water consumption is large and wastes a lot, and China is a country with relatively scarce water resources. The vigorous promotion of water-saving irrigation technology has made on-demand irrigation and precision irrigation mainstream. [0003] The current moisture monitoring system uses the measurement data of one monitoring point to reflect the moisture content of an area. Due to the complex soil composition of each area, the soil moisture content in a small area is special. Obtaining the moisture content by this measurement method has a great impact. O...
